This invention relates to new and useful improvementsin plaster and stucco grounds or bases particularly adapted for use in constructing plaster ceilings and walls, stucco walls and overcoating, tiled floors and walls, porch floors, and in fact for any kind of work requiring a base or reinforcement for cementitious material.

An important object of this invention resides in theprovision of a device of the above character including continuous surface material and novel means for retaining reinforcing metallic fabric in spaced relation thereto a in order that the cementitious material applied thereto will completely embedthe metallic fabric and'be securely keyed to the base Another, important object of the invention is to provide stay or retainingelements which serve as stays orreinforcements for the continuous surface material and which are pro vided with'means whereby they are substantially integrally joined with'the metallic fabric which is in full tension. or fully stretched whereby there will be absolutely no movement of the metallic fabric under expansion or contraction of the cementitious material applied thereto and whereby the metallic fabric will be rigidly spacedfrom the continuous surface material to insure its complete incorporation in the cementitious material and act as reinforcing means therefor. a

Heretofore plaster bases ,have been ad: vanced in which the metallic fabric hasbeen solderedto portions of retaining elements which are exposed through the continuous surface material, butin these instances no provision is made forspacing-the metallic. fabric from the continuous surface material,

- since theexposed portions of the retaining i been of'a construction lacking the fully tensioned Wires so that upon expansion or contraction of the cementitious material these wires become stretched or loosen-ed "sothat they do not form serviceable plaster keying means.

In other attempts the metallic fabric has been attachedto the retaining elementsby staples, coils of wire and the-like which per-' mit relativemovement of the metallic fabric and the retaining elements with obvious det rimental effects to the cementitious material applled thereto. In some of these cases, no paper backing has been used sothat they are;

not adaptable for universal use, as forexample in connection'with plastering interior walls because of the excessive amount of 1 cementitious material that would beusedbecause of no backing forregulating the amount thereof applied to a given-surface. With my invention I have overcome. all ofthese' serious defects in previously known devices of thischaracter'andhaveprovided a plaster or stucco base which is of extremely simple construction, easily manufactured and easily" applied in building constructions. V 1

Otherobjects and advantages of the invention will become apparent during the course of the following description. 1 i

In the drawing wherein like numerals are employed to designate like the several views: I 7

- Figure 1 is a plan of a section of my improved stucco and plaster'base' in which the ordinary flat construction paper 'incorporated; I g I a Figure 2 is a similar view of the same in which" corrugated board or' paper is I em ployed. Y i Figure 3 is an enlarged section of part of partsthroughout a: v

thefbasetaken on the line3 3 of Figure-l.

Figure 4 is an enlarged section taken'on the line L-A of Figure 3. v Figure 5 is anenlarged section of the modification shown in Figure 2 takenonthe line 5-5 of Figure 2. Q

Figure 6 is a similar section of the modification in which corrugated. paper backing is employed with the corrugations thereof 7 extending transversely of the retalning wires.

1 Referring nowmore' particularly to the I drawing, the numeral 7 designates a sheet of transportation and installation, it usually being made in flat sheets, approximately fifty inches by fifty inches, or if desired it may be made in great lengths to 'b'e'rolled for transportation.

On one side of this paperbacking 7, retaining elements 8, preferably, but not necessarily, of galvanized wire, are attached. at spaced. intervals. These retaining wires 8 may be placed any suitable distance apart,

but I find that they may be spaced reasonably far apart, as for example, the distance between upright studs in building constructions. At spaced'intervalsalong the length of each retaining wire, anoifset bend or i crimp 9 s formed therein, it being observed from Figure 3 that these crimps have apices and are extended'through punctures or per forations 10 in the paper backing 7 to extend asubstantial distance beyond the front face of the backing 7 To the exterior ofthe apices of the crimps on the side of the paper backing opposite that on which-the retaining wires 8 are disposed,'I integrally attach strand wires 11, of a metallic fabric 13, by spot-welding,

soldering or the-like. The stay wires;12 of the wire fabric 13 extend at rightangles to,

the stay wires 11 and are preferably-spotwelded to the same at their points of intersection. I

It is to be noted that the strand and-stay pansionor'contraction of the cementitious material. 7

It is also to be particularly noted from Figure 3 thatthe wire fabric 13 is-substantially integrally connected .to the retaining wires 8 so that there will be no relative movement therebetween and in order that the wire fabric will be retained in substantially spaced relation to the paper backing 7 so that it will be completely embeddedin the cementitious material to form a thoroughly rigid reinforcement therefor.

In Figures 3 and 4 I have'illustrated the manner in which the retaining wires 8 will abut'studding 14 when the plaster ground is employed. for interior. plastering, it being "understood that portions of the paperback lng adjacent the retaining wires will likewise find footing-against the studding to additionally support the material during the application of the cementitio-us material. Due to the fact that the retaining wires 8 abut the studding, it will be apparent that the wire fabric 13 will be rigidly supported in spaced relation to the paper backing and studding. l/Vhen the stucco base is. used in exterior stucco work or overcoating, the retaining wlres 8 as well as the paper backlng will fiIId'fOOtIHg against the sheathing 1n a man-' 'ner well understood in theart. x

In the modifications'disclosed in Figures 2, 5 and 6, the only differences in the construction. of the stuccoand plaster base is that corrugated paper backing is employed instead of the smooth fiat backing 7 'as'previously described in order to add rigidity to the plaster base, I V

In Figure 5 the corrugatedpaper backingis designated by the 'numeral15 and the cor-- rugations thereof extend longitudinally of;

punctures o'r perforationslO arranged in thesame manner as the perforations 10'of the'hereinbefore described embodiment. If desired, an additional sheet of smooth flat.

paper backing 16 may be suitably secured to the back of the corrugated paper 15 to enclose the retaining wires 8 within the corrugated sheet. Of course, thewire'fabric1 3 is fully tensioned and is spot-welded'to the-a-pi'ces of the retaining wire crimps 9as the preced ingembodiment. i 1 1 1 In Figure 6, the corrugated paper backing 15isarranged so that its corrugations ex; tend at right angles to the position of those shown in Figure 5, or in other words'paral lel with the strand wires 11 of the wirefabric 13. This modification is otherwise identically'ofthesame construction as the forms disclosed in the other figures of the drawing, andtherefore, a further detail description thereof is thoughtunnecessary;

c It is to be understood that variouschanges in the size, shape, arrangement and construction of the various parts may be resorted to without departing from the spirit of the invention or thescope of theappended claims.

-I-Iaving described-my invention I claim:
